Whether you need a single replacement sensor or controls for an entire BMS project, our experienced team can help.

HVAC Sensors & Transmitters

Our BMS sensor range includes:

  • Temperature sensors

  • Humidity sensors

  • CO₂ sensors

  • Air-quality sensors

  • Differential-pressure sensors

  • Pressure transmitters

  • Duct sensors

  • Outside-air sensors

  • Room/space sensors

  • Immersion sensors

  • Water and pipe temperature sensors

Products are available with commonly used BMS outputs including 0–10 V, 4–20 mA and resistance-based temperature outputs, depending on model.

Control Valves & Actuators

Source control valves and actuators for HVAC and building-services applications from manufacturers including Belimo and Siemens.

Our team can assist with selecting or replacing:

  • 2-port and 3-port control valves

  • PICVs

  • Ball valves

  • Butterfly valves

  • Modulating actuators

  • On/off actuators

  • Spring-return actuators

  • Valve and actuator replacement combinations

Replacing an old actuator? Send us the existing part number.

Energy & Heat Metering

Western Automation supplies metering products for monitoring building energy consumption, including Kamstrup MULTICAL thermal energy meters and associated equipment.

Applications include heating, cooling, energy monitoring and integration into BMS systems.

HVAC Variable Speed Drives

Control pumps, fans and air-handling equipment with dedicated HVAC drives including:

ABB ACH580
Danfoss VLT HVAC Drive FC 102
Schneider Electric Altivar HVAC drives

Need help selecting a drive?

Send us the motor kW, supply voltage, current and application and our team can assist with selection.

BMS Integration & Energy Monitoring

Our wider building-controls range includes energy monitoring, metering, gateways and integration products designed to help BMS engineers connect, monitor and optimise building systems.

One Supplier for Your BMS Project

Instead of sourcing sensors from one supplier, actuators from another and drives from somewhere else, send Western Automation the complete controls schedule.

We'll help source the requirement across our building-controls supplier portfolio.

Supporting BMS Engineers Across the UK

Western Automation combines specialist building-controls knowledge with the product range of a major electrical and automation distributor.

That means one enquiry can cover BMS sensors, valves, actuators, HVAC drives, energy meters, electrical control products and panel components.

For project quantities or regular requirements, ask our Bristol team about trade and project pricing.
